20100314945 | BIDIRECTIONAL CONVERTER AND ELECTRONIC DEVICE - Provided is a bidirectional converter which has flexibility to be applicable in various conditions and performs stable switching of operation mode at high efficiency. An electronic device which supplies power in various conditions and operates with excellent efficiency is also provided. An electronic device is provided with a bidirectional converter, which has a reactor and four switches between power supply input terminals and a secondary battery, and a system circuit is supplied with an operation voltage through the bidirectional converter. A status signal indicating the operation status of the system circuit is transmitted to a microcomputer of the bidirectional converter, and based on the status signal, switching of operation mode of the bidirectional converter is controlled. | 12-16-2010 |
20100283442 | DC-DC CONVERTER AND SEMICONDUCTOR INTEGRATED CIRCUIT FOR CONTROLLING POWER SOURCE - A control technology which eliminates the need for changing the switching frequency even under light load where the on-time of a drive switching element becomes shorter than a minimum on-time dependent on the characteristics of the circuit in a synchronous rectification switching regulator. The synchronous rectification switching regulator includes a drive switching element for storing energy in a coil by applying a DC input voltage from a DC power supply to an inductor and permitting a current to flow, and a rectification switching element for rectifying the current of the inductor during an energy discharge period where the drive switching element is turned off. The timing for turning off the rectification switching element under light load is delayed so as to store energy in the inductor from the output, and the on-time is controlled to become longer as the load becomes lighter by the output from an error amplifier. | 11-11-2010 |
20100245188 | ANTENNA UNIT HOUSED IN AN OUTSIDE MIRROR - In an antenna unit including a dome-shaped top cover, an antenna module disposed in the top cover and adapted to receive radio waves, a bracket covering an under surface of the top cover, and a gasket disposed between the top cover and the bracket to thereby ensure hermeticity in the top cover, the bracket includes a bottom portion pressure welding the gasket between the bottom portion and the top cover to make inside of the top cover an enclosed space, and a mounting portion integrated to the bottom portion to enable the antenna unit to mount in a narrow-mounting-space cabinet. | 09-30-2010 |
